Pax7 and superior collicular polarity: insights from Pax6 (Sey) mutant mice.
Article in Experimental brain research, 2007. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Pax genes are important modulators of CNS development. Pax7 and Pax6 polarise the neural tube and regionalise the brain. Pax7 is pivotal in specifying the superior colliculus/tectum, an important centre for integration of visuomotor responses and a target for Pax6+ retinal ganglion cell axons during retinocollicular mapping. Whilst initial Pax7-specification of the mesencephalon is well-established, a role in regulating polarity within the maturing mouse superior colliculus is yet to be defined, although already detailed for the chick tectum. We therefore quantified Pax7 cellular distribution and expression levels at three functionally distinct stages of superior collicular development, and analysed Pax7 expression in response to aberrant axonal input and altered forebrain/midbrain boundary placement in Pax6 mutant mice. Comparative expression profiles of ephrin-A2 and its co-localisation with Pax7 were determined in wildtype and Pax6 mutant mice. Results indicate that graded Pax7 expression in wildtype mice is perturbed in Pax6 mutant mice; changes manifest as a shift in polarity, loss of graded expression and dramatically reduced protein levels during RGC synaptogenesis. Ephrin-A2 expression is similarly altered. These results implicate Pax7 as an important determinant of polarity within the mouse superior colliculus, and suggest a role in retinotopic mapping.
